A millimeter-wave (mm-wave) radio-over-fiber (RoF) system based on unlocked heterodyned light sources and self-homodyned RF receiver is proposed and demonstrated. Since the mm-wave signal is generated through the beating of two independent optical signals at the photodetector, complexities of the generation and distribution of mm-wave signal in the optical domain are avoided. Also, as RF self-homodyning...
Two millimeter-wave radio-over-fiber signal-generation schemes are demonstrated by heterodyning unlocked-lasers and homodyning the detected RF-carrier to cancel phase-noise effects at baseband. The proposed schemes avoid phase/frequency locking, high-speed modulators and local-oscillators at CS and BSs.
A simplified millimeter-wave radio-over-fiber system is demonstrated experimentally by heterodyning unlocked light sources and homodyning the RF signal at the receiver. The technique avoids phase/frequency locking, high-speed modulators and local oscillators at CO and BSs.
